Shotcut is an Open Source, cross-platform video editor for Windows and Linux capable of converting and editing video files in various formats.
Shotcut supports many audio and video formats and codecs thanks to FFmpeg (or libav as-built) and many image formats such as BMP, GIF, JPEG, PNG, SVG, TGA, TIFF, as well as image sequences. Shotcut requires no importing - native editing and includes frame-accurate seeking for many formats.
